60mm Macro: I've heard things improved a tiny bit with firmware, but not radically, so honestly there's little use for that 60 now that the 56 exists, and is so wonderful. There are also now macro extensions that really put that last nail in the coffin of the poor 60.
"What are considered the fastest focusing Fuji lenses?" - I generally read that the 14 (which I own) is perhaps the fastest, along with the newest zooms (18-135, 16-55, 50-140?). Personally I find the 35 to be perfectly fine, albeit "noisy" compared to the others. I like the little shuffling noise it makes, and I find the AF performance perfectly fine 95% of the time. And when it isn't, well, that's why I got the XT1 and its enormous EVF and focusing aids. When I borrowed the 18-55 kit zoom from a friend for a 5 week vacation, I nearly had a heart attack when I first started focusing with it. It is SILENT, and FAST, compared to what I was used to. It can be fooled once in awhile (what lens can't), but nothing moves on the lens when it focuses (unlike the 35, which extends and retracts slightly), and the little internal motors just do their job so quickly and quietly that it was like I blinked and POOF it was in focus. I'm still very impressed with the AF on the 18-55.
On being hooked on fast glass - I'm with you, much to my wallet's chagrin. So the 23 and/or the 35 would be your everday walkaround lenses, depending on your preferred length. And if you can swing the $, the 56 is of course a stunning, epic piece of glass. Having said that, OIS on the 18-55 makes the 2.8 at the wide end really formidable unless your subject is dancing in the dark. I wrestle constantly with the 18-55 vs all the other new options. None of them have its speed AND OIS. It's one or the other. I wind up being unable to convince myself to shell out for the 16-55 constant 2.8 zoom, because I don't really care about weather resistance, but I DO care about shutter speed. In summary, the 18-55 is improbably, amazingly still the most compelling "do it all" lens Fuji makes, for me. I am, in fact, thinking very hard about trading my 14 lens for one straight-up.
